Sulfur Analysis<br />
Rt®-XLSulfur Packed/Micropacked Columns<br />
• Optimized <strong>columns</strong> for low pbbv sulfur analyses.<br />
• Eliminate the need for Teflon® tubing.<br />
• Column and end-fittings are Sulfinert® treated for maximum inertness.<br />

Specialty Packed/Micropacked Columns<br />
Sulfur analyses are traditionally performed using Teflon® tubing to improve column<br />
inertness. Unfortunately, Teflon® tubing is gas permeable, difficult to pack with high<br />
efficiency, prone to shrinkage, and has poor thermal stability. The Rt®-XLSulfur packed<br />
or micropacked column eliminates these problems. The packing material for<br />
Rt®-XLSulfur <strong>columns</strong> is extensively deactivated for analysis of low ppbv levels of<br />
hydrogen sulfide and methyl mercaptan. It is then treated to achieve effective separation<br />
of hydrocarbons from sulfur compounds. The interior wall and the end-fittings of the<br />
Rt®-XLSulfur column are Siltek® treated, making the column as inert as Teflon®. The<br />
extra care taken to manufacture this column ensures more accurate analyses of sulfur<br />
compounds.<br />
